Oracle DBA Lead at Coforge Limited, leading Oracle 19c RAC implementation for the UCO Bank Treasury Project.

At Coforge Limited, I’m leading Oracle 19c RAC implementation for the UCO Bank Treasury Project, with a focus on high availability and performance. I manage database installation, configuration, patching, upgrades, and migrations.

I lead a team of Oracle and SQL Server DBAs and drive automation and performance tuning initiatives. I also implement ITIL-based processes for service delivery.

At Infosys Limited, I led a global DBA team supporting Oracle databases for GlobalFoundries. I directed migrations and upgrades across hybrid infrastructure, including AWS RDS, and orchestrated Data Guard disaster recovery drills.

Earlier, I supported banking and financial databases at Cognizant Technology Solutions and Tata Consultancy Services Ltd. My work included Oracle RAC migrations, backup and recovery, performance tuning, patching, and disaster recovery.
